If you take a trip to space, you will be back on earth taller.
Well yeah it is not a myth, if you don’t trust me there is a proof, the astronaut Scott Kelly was on space and it returned back to earth 5 cm taller than he was when he took off from the planet.
This phenomenon its caused by the lack of gravity, producing the expansion of our spine discs.
NASA informed this on an interview with CNN.
But sadly this effect it’s just temporary. NASA will submit on a study this stretching, and if it this may cause side effects on the spine.
